IPC: F42C1/00
Filed: 1953-05-15
Abstract: 736,250. Ammunition projectiles and fuzes therefor. BROMBRINI PARODI-DELFINO SOC. PER AZIONI. May 15, 1953 [July 9, 1952], No. 13635/53. Class 9(1) The projectile shown in Fig. 1 has a casing 1 containing an incendiary charge 2 and a hollow explosive charge 3. Axially arranged in the hollow charge is a metal holder 4 containing a detonating charge 6 held in place by a plug 5. Resting on the holder 4 is a flash-tube 7 closed at the forward end by a cap 8. A percussion cap mounted in the nose of the shell comprises a metal cup 9 containing a sensitive charge 10 resting on an igniter charge 11 which in turn is supported by a disc 12. The casing 1 is formed by a stamping operation from a steel block and grooved to receive a driving band 13, the outer diameter of the casing being nearly constant, while the inner diameter tapers so that the casing is thicker towards the base. The detonator is pressed into the bursting charge 3, which, like the incendiary charge 2, is pre-cas before insertion into the shell. After insertion of the detonator, the forward end of the shell i shaped to form the nose and secure the flash tube in position. The casing is then milled to receive the percussion cap 9-10, the disc 12 i then inserted and the igniter charge 11 place( in position before forcing in the percussion cap The cap filling 10 is compressed and lacquered and covered by a disc of lead, tin or paper. On impact the percussion cap 9-10 ignites the charge 11 and the flash passes through the tube 7 to initiate the detonator, which, in turn, initiates the bursting charge 3 and incendiary mixture 2 In a modification, the cavity in the explosive charge 3 is omitted, so that the charges 2,  may be larger. In a further modification an armour piercing head of hardened steel is pro vided, the nose ignition assembly being com pressed within a holder which is inserted in the head and held in position by chamfering the casing.

Title: Process of improving the service properties of cellulosic textile materials
IPC: D06M13/35
Filed: 1963-04-05
Abstract: Cellulosic texture materials, e.g. fibres, yarns and woven and knitted fabrics comprising cotton or regenerated cellulose fibres, are creaseproofed by treating them with substances capable of reacting with cellulosic hydroxy groups and causing the reaction of the substances with the cellulosic material to take place at a temperature of 10 DEG -60 DEG C at a water content of 3-10% by weight by contact with an acid or acid precursor having a pH value below 2, e.g. nitric, hydrochloric or sulphuric acid, or with an alkali having a pH value over 12, e.g. sodium hydroxide in a homogeneous mixture, i.e. a solution or emulsion, with an organic liquid or organic liquids inert to these acids or bases.  The treatment may be carried out in one or two stages, the material either being treated with a solution or emulsion containing the substance capable of reacting with the cellulose together with the acid or alkali and water or being first treated with an aqueous solution containing the substance capable of reacting with cellulose, excess solution being squeezed or sucked off and the material dried and then being treated with the inert organic liquid containing the required amount of water and the acid or alkali. Substances capable of reacting with the cellulose at a pH value below 2 are formaldehyde, polyoxymethylene, acetals and compounds derived therefrom, aminoplast precursors e.g. methylol compounds of urea, ethylene urea, thiourea, dicyandiamide, guanidine, urethanes, acid amides of mono-and polybasic carboxylic acids having 1-5 carbon atoms, octadecyl ethylene urea, alkylcarboxy N-substituted melamine resin, stearylmethylamidomethylene pyridinium chloride, aminotriazines and triazones and their etherification products, and substances capable of reacting at a pH value above 12 are mono-and di-chlorotriazines, vinyl sulphone compounds and their derivatives, acryl-amide compounds and monoepoxy and diepoxy compounds, e.g. diglycide ether.  Suitable organic liquids are carboxylic acids and hydroxycarboxylic acids having 1-6 carbon atoms, primary and secondary alcohols, ketones, esters, acetals, hydrocarbons and liquid aromatic compounds.  The organic solvents may also contain water combining salts, e.g. calcium chloride, to maintain the desired water content.  When a two-stage process is utilized fabrics may be embossed between the two stages.  After impregnation the material may be stored for from 15 minutes to 18 hours in a rolled up or laid condition until the reaction is complete.

Title: Improvements relating to door and similar holders
IPC: E05C17/02
Filed: 1927-05-23
Abstract: 285,700. Snaith, J. May 23, 1927. Stays.-A stay-bar a of the kind which is slidable over a headed pin v<1> and arranged so that the parts cannot be disengaged until the cabin door or like hinged member is in the closed position, is provided with an attachment for the bar so that it can only be detached from the door or the door frame on which it is mounted by a rotary movement, this movement being prevented while it is in engagement with the pin. The headed pin may be mounted on its support in a similar manner. The. tubular bar a is attached to a plate g having a screwed socket, and a plate k secured by screws m to the door frame carries a screw j. The bar is attached to the frame by rotating it so that the plate g screws over the pin j, screws r then tightening the plate g on the under plate k to cover its screws m and render them inaccessible to a thief on the outside of the door. The pin v<1>, carried by a bracket w on the door p, may be engaged with, and disengaged from, the stay-bar through the enlarged slot s<1>. Under the head of the pin is a neck v<2> that slides along the slot s of the tubular bar as the door is opened, this opening movement being limited by an end enlargement s<2> of the slot, which is uncovered when the piston t is pressed back. The spring-pressed piston acts against the pin in the slot s<2> and prevents rattling of the open door. The bar is mounted for universal movement on pins c, d<2>, a projection q serving to hold the bar horizontal when disengaged from the headed pin.

Title: Improvements in and relating to permutation locks
Inventor: JOHNS-HUNT JOHN
IPC: E05B37/08
Filed: 1956-05-04
Abstract: 815,654. Permutation locks. CHUBB & SON'S LOCK & SAFE CO. Ltd. Feb. 11, 1957 [May 4, 1956], No. 13910/56. Class 44 In a permutation lock comprising a driver 8 adapted to be engaged by a fence lever 4 so as to withdraw a bolt 3, snapaction strip spring means are provided which move between a position in which the fence lever is restrained from engaging the driver, and a position in which the fence lever is free to engage the driver. As described, the strip spring means (see Figs 5 and 6), is E-shaped, the centre limb 13 being longer than the outer limbs 14 and having a T piece 15 which engages a recess 17 in a substantially L-shaped plate 12. The centre limb lies in a slot 16 extending from the recess, and the extremities of the limbs 14 engage grooves in the plate edge on either side of the slot 16, the relative length of the limbs being such that the outer limbs 14 are bowed, as in Fig. 6. Stops 18, 19 limit the movement of the spring means which normally lie adjacent the stop 18, as in Fig. 6, with an abutment 20 formed on the bridge of the E-shape engaging a chamfered edge 22 on the fence lever 4 which is thus held out of engagement with the driver 8. Axial movement of the shaft 7 causes an abutment 23 formed on the rear face of the driver 8 to engage the limb 13 of the strip spring which is thereby snapped into engagement with the stop 19 permitting the lever 4 to drop into engagement with the notch 9 of the driver. Axial movement of the shaft 7 to its original position disengages the abutment 23 from the limb 13 thus enabling the strip spring to snap back into a position where the nose of the abutment 20 engages the side of the lever 4. Rotation of the operating knob to disengage the lever 4 from the driver 8 brings the chamfered part 22 adjacent the projection 20 which thus causes the lever to move wholly out of engagement with the driver. The correct angular position of the driver to bring the abutment 23 adjacent the limb 13 is indicated by a reference mark on the lock face. A semi-circular ridge on the rear plate of the lock in conjunction with abutments 25 on the driver prevents axial displacement of the shaft unless the driver is correctly positioned, and prevents rotation of the shaft when so displaced. An anti-picking device comprises a stud on the rear plate which passes through a hole 28 in the plate 12 and holds a spring-urged dog out of engagement with the bolt. Removal of the rear plate releases the dog which then engages the bolt to hold it in the locked position. Specifications 705,729, 735,148, 748,360, 761,432 and 763,597 are referred to.

Filed: 1966-03-31
Abstract: 1,131,628. Purifying combustible gas. POWER-GAS CORP Ltd. 31 March, 1966, No. 14312/66. Heading C5E. Combustible gas from the catalytic steamreforming of hydrocarbons under pressure is purified, after passing through a carbon monoxide conversion stage by being contacted first with water containing CO 2  from a second water-contacting stage, and then, after a major portion of the cooled gas has been led off, by passing the rest of the gas through the second water-contacting stage to absorb CO 2  from the gas. The portion of cooled gas led off may be enriched with methane or vaporized liquefied petroleum gas to make town gas, and the H 2 -rich gas leaving the second watercontacting stage may be recycled to a hydrodesulphurization stage preceding the steam reformer. The water from the first contacting stage may be passed to a tower for regeneration with air, for recycling to the second stage. This stage may be superposed on the first stage, as in Fig. 1 (not shown), or may comprise separate vessels, Fig. 2 (not shown), a compressor sucking the minor gas portion to the second stage. A specific example is described.

Title: Method and apparatus for dividing plastic substances by volume
IPC: A01J21/02
Filed: 1957-05-07
Abstract: 856,029. Moulding blocks of margarine &c. UNILEVER Ltd. May 7, 1957 [May 8, 1956], No. 14545/57. Class 87(2). Apparatus for dividing plastic substances by volume, comprises a casing 6 having a diametrically opposed inlet 7 and outlet 8, a cylinder 9 rotatably mounted in the casing and provided with a channel 10 perpendicular to the axis of rotation, which channel in one position of the cylinder 9 is in alignment with the inlet and outlet, and a divided piston 11 movable in the channel 10, the piston having two parts 12, 13 capable of independent motion with respect to each other. The two parts of the piston 11 are biased towards one another by means of a spring 16 supported between extensions 14 and 17 of the piston parts 12 and 13 respectively. To and fro motion of the piston parts 12, 13 is limited by a stop member 20 which co-operates with surfaces 18, 19 on the piston parts. The stop member 20 is conical in shape and is adjustable in position by means of an axially movable axle 21. Movement of the piston 11 in the channel 10 is effected by means of a lever 27 pivoted at 29 and extending through a slot 33 in a push rod 30 into engagement with rollers 23, 24 carried by the piston 11. The push rod 30 is moved to and fro by means of an arm 36 pivoted at 37 and provided with a curved track 38 to co-operate with rollers 31, 32 on the push rod 30. The lever 27 and push rod 30 are carried by an attachment 28 of the cylinder 9, all these parts being intermittently rotated through 180 degrees by means of a drive shaft 22 connected to an electric motor (not shown) by means of a Geneva movement or cam gear. This motor may also provide the drive for the arm 36. Operation. A material such as margarine is fed through the inlet 7 under pressure or by gravity or by the suction effect of the piston 11. Movement of the piston part 12 towards the outlet 8 is limited by the stop member 20, but the piston part 13 is moved an extra distance to project beyond the surface of the cylinder 9, this movement being produced by the lever 27 and permitted by the spring 16. The measured quantity of material is then separated by means of a knife or wire (not shown) either at the edge of a discharge mouthpiece or from the end surface of the piston part. The ejecting surface of the piston part 13 is retracted flush with the surface of the cylinder 9 before further movement of this cylinder.
